FRANK PERCY BUNKER, OF NORTH M'ANCHESTEB, INDIANA.

ERICK-MOLD.

Specification of Letters Paten Application filed March 22, 1918.I Serial No. 223,924.

To all whom it may concern:

Beit knownthat' I, FRANK PERCY BUNKER, a c1t1zen of the United States, residing at North Manchester, in the county of Wabash and State of Indiana, have invented a new and Improved Brick-Mold, of which the 4 following is a full, clear, and exact description; V

My invention relates to a collapsible brick mold, and an object of the invention is to provide a mold which is simple, inexpensive,

and which allows the use of a series of botpartitions,

toms. of the mold with one set of walls and so that bricks may be cured and hardened on the bottom of the mold while thelrest of the mold is used over and over again to form new-bricks on new bottoms of the mold.

With the above and other objects in View,

.the nature of which will more fully appear asthe description proceeds, the invention consists in the novel construction, combiof a side wall of the mold.

has a series of nation and arrangement of parts as herein fully described, illustrated and claimed.

In"the accompanying drawings, forming part of the application, similar characters of reference indicate corresponding parts in all the views. I

I Figure 1 1s a plan of a brick moldemgr bodying my invention;

Fig. 2 is a longitudinal section on line 2-2, Fig. 1;

Fig. 3 is a transversesection on line 3-3, Fig. 1; V

Fig. 1 is a fragmentary plan view of the mold bottom;

Fig. 5 is an elevation of a partition; Fig 6 is a perspective view of an end wall; and

Fig. 7 is a fragmentary perspective view against the lugs by partitions 12 which have extensions 13 fitting into the'slots In Patented J mm 4, 1918.

other words, the distancebetwee'n the slots 9 determines the thickness'of thebrick. V The partitions, in addition, have fnotches 14 which engage the upper edge of the side walls 11 which also have notches '14: engaging lateral extensions 15' of the partitlons 12 in which the notches 14 are formed...

These interengaging notches prevent the walls 11 and partitions 12 fromspreading at the upper edges, the spreading at the lower edges being prevented by the lugs 10 and slots 9.

The side walls right angles to form flanges 15, the two flanges of the same wall pointing in the same The flanges of the opposite walls direction. point in opposite directions, or outwardly of the mold. The flanges 15 are engaged by the folded-over ends 16 of the end walls 17 the end walls 17 being slipped over the flanges 15 of the side wall 16. The engagement of the infolded ends of the end wall 17 with the flanges 15 lock said end walls to the side walls and to the bottom by the engagenient of the extensions 13 rovided on the end walls 17. To facilitate t e handling of the end walls, they are providedwith ips 18. f When a mold is mounted in the manner as shown in Fig. I, the same'can be filled with material from which the bricks are to be made. After the mold is filled, the side wall, end walls, and the partitions can be removed, leaving-the molded bricks onthe bottom 8 to cure and harden. Another bot- 11 have the ends bent at tom is then taken, the removed side and end walls and the partitions are mounted on the new bottom, the mold filled with material, a.

again the side walls, end walls and partitions removed, etc. It will be seen, therefore that with the same side walls, end walls, an titions, a number 'of bricks can be mol that is, by having a large bottoms to support the bricks after the have been molded .while they cure an harden. I

I claim:

number of mold t 1. A collapsible brick mold com rising an elongated bottom having paralle ly-spaced slots disposed transversely of the bottom, lugs near the side edges ofthe bottpm, side Walls on the bottom havingv outwardly-d1- reeted flanges at the vertical edges, end Walls having infolded vertical edges for engaging the flanges of the side walls, said end walls having extensions adapted to engage the slots of the bottom, and partitions adapted v to be disposed transversely of the bottom between the side walls and adapted to maintain said side walls against the lugs, said partitions having extensions for engaging slots in the bottom and notches forengaging the parallel edges of the side walls, said side walls ha'ving also notches in the upper edges adapted to engage the partitionsat the posed transversely oi f vthe side Walls to maintain said side walls said partitions having notches in the partitions.

23A collapsible brick mold comprising arr-elongated ottom, lugs near the side edges of the bottom, partitions adapted to be disthe bottom between against the lugs,

means for detachably engaging the bottom and side walls, said side walls having their vertical ed es bent outwardly,

and end walls having their vertical edges folded over so as to engage said outwardly bent ends of the side walls. I

3. A collapsible brick mold comprising an elongated bottom having parallelly-spaced slots disposed transversely of the bottom, i lugs near the side edges of the bottom, side" 5 Walls on the bottom, end walls detachably engaging the vertical edges of said side I walls, and partitions adapted to be disposed transversely of the bottom between the side walls for maintaining said side .walls against the lugs, said partitions having extensions forengaging the slots in the bot tom, said extensions-being narrower than the J partitions so that said partitions have por- V tions thereof resting on the bottom, said partitions having also edges near the top for 1 u and said side walls having notches to engage the a Y engaging the top edges of the side walls,

partitions at the notches in the partitions.
